MANDIBULAR SUBCONDYLAR FRACTURE PDF

Perhaps no area of facial trauma has inspired more controversy than the management of mandibular subcondylar fractures. Fractures of the condylar region. Clinically, this equates to open treatment of condylar neck fractures or subcondylar (caudal) fractures (A). The surgeon may elect to place one or two plates. Background and objective: Mandibular fractures are the most frequent and sub condylar region is a common site of fracture. Proper.

Temporomandibular joint morphology following post-traumatic ankylosis in 26 patients. This approach provides a direct approach to the high subcondylar region and the distance from the skin incision to that region is reduced, compared to that of the routine retromandibular approach.

With enhanced experience of the surgeons toward the endoscopic technique the controversies over the right treatment choice would slowly subside. The wound is also reapproximated in layers, and the SMAS is resuspended.

Isolated fractures of the coronoid process should be viewed with suspicion and fracture of the ZMC should be ruled out. Although surgical management has been attempted in the frcture of obtaining better results, some problems have remained, including difficulty in accessing the fracture site and insufficient or failed reduction of the fracture. August 26,Quality control: Other fractures of the body, are classified as open or closed.

Towne’s view of a manribular condyle fracture. Int J Oral Maxillofac Surg.

Closed versus open operative treatment of nondisplaced diacapitular Class VI fractures. Maxillomandibular fixation with circumdental wires, archbars and elastics for a condyle fracture. The more complicated the fracture infection, comminution, displacement the higher the risk of fracture. Traditionally, plain films of the mandible would be exposed but had lower sensitivity and specificity owing to overlap of structures.

Surgical versus non-surgical treatment of fractures of the articular process of the mandible.

Mandibular fracture

Fractures at a level where there is inadequate space for two holes to be drilled for the plate B require special techniques of osteosynthesis. Sign in to customize your interests Sign in to your personal account.

The results of the analysis performed on our model are shown in Fig. Therefore, we measured the biomechanical load of four different two-plate fixation techniques in an experimental model of the mandibular subcondylar fracture [ 5 ]. Throckmorton GS, Ellis E. Commonly, a blow to the ipsilateral mandible causes a contralateral fracture in the condylar region.

The study of conservative treatment of condylar fractures carried out by Zachariades et al. Authors using the endoscopic method to treat subcondylar fractures believe that a single intraoral incision would be sufficient to reduce a laterally displaced condyle.

Received May 6; Accepted Jul A systematic review was unable to find sufficient evidence of the superiority of one frzcture over another in the management of condylar fractures.

Mandibular Subcondylar Fractures: A Review on Treatment Strategies

Closed reduction with direct skeletal fixation follows the same premise as MMF except that wires are passed through the skin and around the bottom jaw in the mandibule and through the piriform rim or zygomatic buttresses of the maxilla then joined together to secure the jaws.

Maxillofacial injuries in western Iran: CT or digital volume tomography DVT imaging may be used as an alternative. Endoscope-assisted transoral reduction and internal fixation versus closed treatment of mandibular condylar process fractures-a prospective double-center study.

Cysts and tumours can subcondylwr effective bone to bone contact and osteomyelitis or osteonecrosis compromise blood supply to the bone. Mandibular fracture is a rare complication of third molar removal, and may occur during the procedure subconxylar afterwards.

Loss of consciousness combined with aspiration of tooth fragments, blood and possibly dentures mean that the airway subconxylar be threatened.

When the maxillary top and mandibular bottom teeth are aligned together, this brings the fracture segments into place. Management of mandible fractures has been mentioned as early as B.

This is the most useful classification, because both the signs and symptoms, and also the treatment are dependent upon the location of the fracture. These studies imply a need for new concepts for the application of osteosynthesis plates at the posterior and anterior border of the condylar neck in order to restore tension and compression trajectories [ 8 ]. Acknowledgments This research received no specific grant from the government or any other funding agency in the public, commercial, or not-for-profit sectors.

Abstract Condylar injuries are often subjected to discussion and controversy in maxillofacial surgery as they constitute many of the facial fractures.

They are more often combined with other mandibular fractures. B It provides good visualization of the lower subcondyle and allows straightforward fracture management.

Surgical Management of a Mandible Subcondylar Fracture

This protocol is also applicable to bilateral fractures in which the fractured segments are not displaced. However several radiologic studies demonstrate a better anatomical reduction after the ORIF treatment 1945 — Those approaches provide good visualization of the subcondyle from the posterior edge of the ramus, allow the surgeon to work perpendicularly to the fracture, and enable direct fracture management.

September 03, Conflict of Interest: Some publications, state no marked difference between the results of open or closed treatments 1619 — The periosteum at the posterior border of the ramus is then incised, and subperiosteal dissection is continued to the condylar area until the fracture line and the displaced or dislocated proximal fragment are identified.
